Services
What we do for homes and businesses.
Everything we take on for homes and businesses across West Kent — what's involved in each, and the promises we stand behind.

R1 Residential
Whole-house renovations
Renovating a house end to end, usually while it's empty — a full strip-out, new services, and every room finished to the same standard. Most take between twelve and twenty weeks depending on size and structural work.
Includes
Strip-out and disposal
Plastering and joinery
Flooring and decoration
Rewiring and replumbing
Kitchens and bathrooms
External repairs
R2 Residential
Extensions & structural work
Rear, side and wrap-around extensions, plus the structural work that opens a house up — steels, wall removals, chimney breasts and new openings. We handle building control and the party wall process with your neighbours.
Includes
Single and double-storey extensions
Foundations and groundworks
Building control liaison
Structural steels and load-bearing removals
Glazing and roof lanterns
Party wall agreements
R3 Residential
Loft conversions
Dormer, hip-to-gable and rooflight conversions, adding a bedroom, office or en-suite. Most are permitted development, and we'll tell you at the survey which route your roof needs.
Includes

Staircase installation
En-suite plumbing
Dormer construction
Insulation and fire regulations
Velux and dormer glazing
R4 Residential
Kitchens & bathrooms
Single-room work done properly — supplied and fitted, or fitted to units you've bought yourself. Usually two to four weeks, and we sequence trades so the room isn't out of use longer than it needs to be.

Tiling and waterproofing
Extraction and ventilation
Plumbing and electrics
Unit and worktop installation
Making good and decoration
